Volvo C30 diesel 2007 - Engine concern - scot22

Sorry this is very vague. The engine does not seem to run as smoothly as before ( 60,000 on clock ) Would any problem show up on dashboard information screen ? or could it not be being picked up before something happens ?
Having written this I realise there is nothing objective possibly query is : how comprehensive is warning system of faults ?

In what way is it less smooth?

More noise?

Does it stutter?

tick over lumpily?

Start less easily?

Does it use more fuel?

Have you changed anything, e.g. switched regular fuel?

Has it been serviced recently? (just remembering when the local lot left the pipe off between air box and turbo on one of mine)

Was it regenerating the DPF when you noticed this? That certainly makes the Outlander rougher.

Volvo C30 diesel 2007 - Engine concern, EML, DPF, P244A, - CliffE
Scott,
I have a 2011 C30 1.6 DrivE that became 'lumpy'. The symptoms changed over weeks to go into Reduced Power, then an EML light and sometimes both warnings/lights. I could reset the fault by turning off the ignition for a few minutes. After a week or so with no warnings the random sequence started again. Volvo Glos reset the warnings/codes and I had a few days without the problem. When the issue started again I took seriously the stories of replacement DPF at circa £800.
I bought a code reader from EuroParts for £44 and noted and reset the codes myself.
The Maxi Scan showed codes P244A $07E8N Generic and P244A 07E8pd
Diesel Particulate Filter differential Pressure, pressure sensor circuit low.

I found resetting the codes seem to suggest DPF not a consistent fault. I checked the pipes to the sensor (fixed to the battery box) and by accident found the C clamp round a heater hose for the twin hose clip is actually in two parts.
Having separated it meant the hoses were bending at the point they leave a mid section metal hose section.
I guess car speed etc where the hoses sit in front of the radiator would make it an erratic pressure to bend the pipes and affect the sensor flow.
Tie-wrapping the pipe work solidly in place didn't fix the problem straight away. Reset faults and they reappeared. Priced new pipe work at Volvo (£130) and rechecked the pipes to see if split - didn't think they were in bad condition so persevered.
Finally (sorry) getting the reduced power warning fault clear and realising the Regen must not have been happening on my many weekend trips (bristol-Liverpool) before the reduced power came back and going straight on the M5 for 25 mins at 3000 revs 70mph ish in 5th gear I stopped and after turning off the ignition and back on again the EML light stayed out. Car is running perfect, Maxi Scan used to diagnose daughters Suzuki Swift engine encoder (£59 to replace) so great value from EuroParts and a seemingly massive set of bills for both cars cost pounds.
